But I felt that there was more to the shot than that. As I stood considering what was missing, I became aware of the bus approaching. Beyond a vague notion of the ‘rule of thirds’, I wasn’t sure what to do with it. As luck would have it, the bus stopped in the bottom right of my viewfinder! Ideally, I’d have liked it a few feet further back – to get more red in shot and to cover the letters ‘ST’. But i like what I got anyway.
